How to compare a metric versus last week or month

[Anonymous]

Hi

I would like to compare my weekly and monthly sales with the previous week or month. How can I do it?

Imagine my data source looks like this

And my final goal is to be able to build a matrix like this

How can I do this?

Last. How can I compare versus a same week or same month last year?

Hi @Anonymous ,

You can create calendar table first of all, create relationship between your data table and calendar table on date field, then create measures like DAX below. You can create for Month sale in the similar template (see the red mark).

DateDim= CALENDARAUTO()
 
CW Sale= CALCULATE(SUM(Table1[sales]),FILTER(ALLSELECTED(Table1),YAER(Table1[Date]) =YEAR(MAX(Table1[Date]))&&Table1[WeekNum] =MAX(Table1[WeekNum])))
 
LW Sale = CALCULATE(SUM(Table1[Sales]),DATEADD('DateDim'[Date],-7,DAY))
 
Vs LW %= IF([LW]<>BLANK(),DIVIDE([CW]-[LW],[LW]),BLANK())

Best Regards,

Amy
